Density of water = 1 gm/mL = 1gm/cm^3
9. The volume of 1 kg water = 1L
10. The weight of 5L of water = 5 kg
11. a. 1.0 x 10^9
b. 1.181 x 10^-1
c. 1.90625 x 10^1 = 19.0625
d. 1.0
e. 4.392 x 10^-10
f. 1.764 x 10^3
g. 3.03 x 10^12
Please rate the solution. Your efforts are highly appreciated. Thank you.
